How do I get the VR Scene Inspection add-on working with the Oculus Quest 2?
i had the same problem but i could solve it.

Switch on your HMD
You have to plug in your HMD with USB to you PC
Start Oculus Link on your HMD
Usually it should start after starting Oculus link the oculus app on windows by itselfe
Now you can start your blender scene
Start VR-Session in Blender
Put on your HMD
Enjoy
